Saves time
in servicing, maintenance and the commissioning of systems.

The new Testo
550 digital manifold provides high performance at an affordable
price. The instrument's intuitive operation allows you to measure
high and low pressure quickly and precisely, and with the two
temperature inputs you can simultaneously calculate superheating
and subcooling. The brightly illuminated display allows fast
and easy readout of all measurement values and there are 31 refrigerants
stored in the instrument, which can be selected via a direct
button.

The ideal tool
for commissioning systems
The evacuation of the system is confirmed for you as the instrument
displays vacuum values. In addition to this, a temperature-compensated
tightness test of the system can be carried out. By measuring
the system pressure and the ambient temperature over a defined
period, the users can make a statement on the tightness of a
system  allowing commissioning to be carried out reliably
with the Testo 550.
